Extracting device for extracting antigens.

摘要

There is described a container used to extract antigens for an immunoassay, having a wall means (14) defining open and closed opposite ends (12, 18). The container is provided with dividing means located in the closed end of the container which divides the volume of the closed end into at least two separate regions. A portion of the container's wall means adjacent to the closed end (18) is shaped and sized to cooperate with a depositing means to ensure that separate reagents (15, 17) are separately deposited on opposite sides of the dividing means (16).
